Abstract
A device that stabilizes a workpiece during processing includes a first workpiece carrier part, a second work piece carrier part, and a fixing unit that mutually fixes the workpiece carrier parts in such a way that the workpiece is held between the first and-second workpiece carrier parts. The first workpiece carrier part has a patterned mask. In this way, the production costs can be significantly reduced particularly in the case of workpieces at risk of fracture.
Claims
exact text as granted — not AI-modified1. A device that stabilizes a workpiece during processing comprising:
a first workpiece carrier part;
a second workpiece carrier part; and
a fixing unit configurable to mutually fix the workpiece carrier parts in such a way that the workpiece is held between the first and second workpiece carrier parts, wherein the first workpiece carrier part comprises a patterned mask, wherein the patterned mask comprises a thickness of about 10 to 250 μm.
2. The device as claimed in claim 1 wherein the second workpiece carrier part comprises a covering plate and the first workpiece carrier part comprises a carrier plate with a mask formed in an integrated fashion.
3. The device as claimed in claim 1 wherein the second workpiece carrier part comprises a carrier plate with a first depression that receives the workpiece.
4. The device as claimed in claim 1 wherein the patterned mask comprises a stencil mask film usable for an implantation.
5. The device as claimed in claim 1 wherein the workpiece is held only at opposite main surfaces.
6. The device as claimed in claim 1 wherein the fixing unit comprises an articulation.
7. The device as claimed in claim 1 wherein the fixing unit comprises at least one mechanical locking element.
8. The device as claimed in claim 1 wherein the fixing unit comprises at least one magnet element.
9. The device as claimed in claim 3 wherein the first workpiece carrier part comprises a supporting element that carries the patterned mask and the second workpiece carrier part comprises a second depression that receives the supporting element.
10. The device as claimed in claim 1 wherein openings in the mask are formed in at least one of a punctiform fashion, in a slotted fashion, in a linear fashion, in a rectangular fashion, or in a round fashion with regard to a plan view.
11. The device as claimed in claim 10 wherein the openings comprise at least one of a rectangle or a truncated cone in cross-section.
12. The device as claimed in claim 1 wherein the patterned mask comprises a metallic material, a ceramic, or a plastic.
13. The device as claimed in claim 1 wherein the workpiece comprises a thin wafer carried on a carrier wafer.
14. The device as claimed in claim 13 wherein the thin wafer has a thickness of about 140 μm.
15. An apparatus for stabilizing a workpiece during processing comprising:
a first workpiece carrier part;
a second workpiece carrier part; and
means for mutually fixing the workpiece carrier pads in such a way that the workpiece is held between the first and second workpiece carrier parts, wherein the first workpiece carrier part comprises a patterned mask.
16. The apparatus as claimed in claim 15 wherein the second workpiece carrier part comprises a covering plate and the first workpiece carrier part comprises a carrier plate with an integral mask.
17. The apparatus as claimed in claim 15 wherein the second workpiece carrier part comprises a carrier plate with a first depression configured to receive the workpiece.
18. The apparatus as claimed in claim 17 wherein the first workpiece carrier part comprises a supporting means for carrying the patterned mask and wherein the second workpiece carrier part comprises a second depression configured to receive the supporting element.
19. A device that stabilizes a workpiece during processing comprising;
a first workpiece carrier part;
a second workpiece carrier part; and
a fixing unit configurable to mutually fix the workpiece carrier parts in such a way that the workpiece is held between the first and second workpiece carrier parts, wherein the first workpiece carrier part comprises a patterned mask, and wherein the fixing unit comprises an articulation.
20. The device as claimed in claim 19 wherein the fixing unit comprises at least one mechanical locking element.
21. A device that stabilizes a workpiece during processing comprising:
a first workpiece carrier part;
a second workpiece carrier part; and
a fixing unit configurable to mutually fix the workpiece carrier parts in such a way that the workpiece is held between the first and second workpiece carrier parts, wherein the first workpiece carrier part comprises a patterned mask, wherein the patterned mask comprises a metallic material, a ceramic, or a plastic.Cited by (0)
